Purpose

The portal home page was static means there's no way for a user to customize what they see. This PR introduces a customizable widget grid, building on the widget infrastructure and pre-approved widgets from PR #714 (My Projects, Quick Actions, Recent Deployments).

While wiring this up, I found two real bugs in @backstage/plugin-home@0.9.6's home page grid component:

  • The Save button was hidden whenever the widget count hit zero, so there was no way to persist an intentionally empty board.
  • The toolbar's resting state required both "not editing" and "at least one widget" to show a clean button — an empty, saved board fell through to the full Cancel/Add Widget/Save toolbar instead of a single button.

Goals

  • Give users a customizable home page: Edit / Add Widget / Save / Cancel / Restore Defaults / Clear All.
  • Wire in the Recently Visited, My Projects, Quick Actions, and Recent Deployments widgets.
  • Fix the two upstream toolbar bugs described above without waiting on a new @backstage/plugin-home release.

Approach

Added homeWidgets.tsx, which wraps each raw widget component with createCardExtension so the grid system can manage it (drag, resize, add, remove). HomePage.tsx now renders CustomHomepageGrid with these widgets, while the permission-gated Platform Details card stays outside the grid since it isn't a personal preference.

For the two upstream bugs, I used Yarn's patch: protocol (yarn patch / yarn patch-commit) against @backstage/plugin-home@0.9.6 rather than forking the whole package or waiting on an upstream release — this keeps the fix as a small, reviewable diff in .yarn/patches/, referenced from packages/portal-app/package.json. The patch:

  1. Makes the Save button render regardless of widget count.
  2. Makes the plain resting-state button show whenever not editing, regardless of widget count, and adds a standalone "+ Add Widget" button for the empty-board case specifically (rather than falling back to Edit, which wouldn't have anything to edit).

Screenshots of the before/after toolbar behavior: (The empty board with "+ Add Widget", The Add Widget dialog listing the five widgets, and The arranged grid)

User stories

As a portal user, I can customize my home page by adding, removing, and rearranging widgets (Recently Visited, My Projects, Quick Actions, Recent Deployments, Starred Entities), and my layout persists across sessions.

Release note

Added a customizable home page widget grid to the portal, along with a fix for two bugs in the underlying Backstage home page toolbar (couldn't save an empty board; toolbar showed the wrong button state on an empty board).

Test environment

  • macOS, local k3d cluster (openchoreo context)
  • Node 22, Yarn 4.18.0
  • Docker (Rancher Desktop / moby engine)
  • Chrome, tested against openchoreo.localhost:8080

Learning

Traced the actual (non-minified) source of @backstage/plugin-home@0.9.6 via the sourcemaps shipped in node_modules to find the real cause of two toolbar bugs, rather than guessing from behavior alone. Used Yarn's patch/patch-commit workflow to ship a minimal, reviewable fix to the dependency instead of forking the package or bumping its version (a much larger, riskier change given how central @backstage/plugin-home is to this app).

Summary by CodeRabbit

  • New Features
    • Added a customizable home-page widget grid with configurable positions and sizes.
    • Added home-page widgets for recently visited items, projects, quick actions, and recent deployments.
    • Widgets load content as needed to support a smoother home-page experience.
    • Starred entities and recently visited items are arranged in the top row by default.
    • Existing search and platform details features remain available.

Remove the unresolved barrel exports

plugins/openchoreo/src/index.ts:35-36 exports two module paths that do not exist. TypeScript module resolution therefore fails when the package index is processed. Remove these exports or add the referenced modules before release.

This patches two real bugs I found in @backstage/plugin-home@0.9.6's home page toolbar, traced through the actual (non-minified) source via its sourcemaps:
(1) the Save button was hidden whenever the widget count hit zero (numWidgets > 0 && guard), so an empty board couldn't be saved, and
(2) there was no dedicated "not editing" state for an empty board, so it fell through to the full edit toolbar (Cancel/Restore Defaults/Add Widget/Save) instead of a clean standalone Add Widget button. This was the cause of the "Cancel button showing up unexpectedly" behavior I ran into and confirmed by reproducing it before and after the patch. I used yarn patch/patch-commit since it's a minimal, reviewable 2-line-and-one-new-branch fix rather than forking the whole package or waiting on an upstream release. But happy to open a follow-up issue/PR against backstage itself if you'd prefer that longer-term. Let me know if you'd like me to walk through it live too.

We don't have to use this patch version. Not allowing to save an empty board is fine, coz ideally home page can not be empty. Can we please stick to proper released version of the home page plugin

@achinthajayaweera Please check the failing tests.
Also you need to sign your commits, please refer https://github.com/openchoreo/openchoreo/blob/main/docs/contributors/github_workflow.md#dco-sign-off
Also the default home page should retain its current view.

Adds a customizable home page grid (Edit/Add Widget/Save/Cancel/
Restore Defaults/Clear All) wiring in Recently Visited, My Projects,
Quick Actions, and Recent Deployments widgets from PR openchoreo#714.

Patches @backstage/plugin-home@0.9.6 via yarn patch to fix two
upstream bugs in the toolbar:
* Save button was hidden whenever the board had zero widgets,
  making it impossible to persist an intentionally empty board
* Resting-state button required both not-editing and zero widgets
  before showing a clean control, so an empty saved board fell
  through to the full edit toolbar instead

…lt layout regression

Fixes three real issues found in PR openchoreo#789's CI run:

* TypeScript compile error: CustomHomepageGrid no longer receives the
  unsupported preventDuplicateWidgets prop (confirmed not present on
  CustomHomepageGridProps in the installed @backstage/plugin-home
  version; already a documented no-op, now removed for real)
* TypeScript compile error: QuickActionsSection's explicit React.FC
  annotation widened its return type to ReactNode, which is
  incompatible with createCardExtension's ComponentParts type;
  removed the annotation to match the existing working pattern used
  by MyProjectsWidget (implicit return type inference)
* Prettier formatting issues in HomePage.tsx and homeWidgets.tsx

Also includes the default-layout fix addressing review feedback that
the home page should retain a sensible default view: added a
defaultLayout config passed to CustomHomepageGrid so first-time users
(and the Restore Defaults button) get the five real widgets instead
of an empty board.

Hi @stefinie123, I’ve replied to both patch questions above. I’ve also pushed a fix for the failing Build/Lint checks (TypeScript errors + formatting) and addressed the “default home page should retain its current view” point.

For this, I added a defaultLayout config so first-time users see the five real widgets by default instead of an empty board. I’ve also verified it live with fresh loads, Restore Defaults, and the empty-state flow, and everything is working as expected.
with restore default option

The workflow run for the new commit is currently awaiting maintainer approval. When you get a chance, could you please approve it so I can confirm that Build/Lint/Codecov are all green?

Thanks so much for the review, and I’m happy to make any further changes.

Default layout should match our exact layout that we have today. No need to add 'MyProjects', 'QuickActions' and 'RecentDeployments'

Per reviewer feedback:
- Removed the yarn patch for @backstage/plugin-home@0.9.6 entirely.
  The two toolbar bugs it fixed are no longer a concern: the reviewer
  confirmed that not being able to save an empty board is acceptable
  behavior (the home page shouldn't realistically be empty), so the
  plain released package is used instead of a patched one.
- Changed defaultLayout to exactly match the pre-PR home page
  (HomePageStarredEntities + RecentlyVisited side by side), instead
  of showing all five widgets by default. My Projects, Quick Actions,
  and Recent Deployments remain available via Add Widget, just not
  shown by default.

Hi @stefinie123, I’ve pushed fixes addressing both points:

  • Removed the yarn patch entirely and reverted to the plain released @backstage/plugin-home@^0.9.6 (resolved to 0.9.9). I also verified that the empty-board behavior you flagged as acceptable now matches the unpatched library exactly.
  • Updated defaultLayout to match the exact pre-PR home page (Starred Entities + Recently Visited side by side), confirmed by diffing against upstream/main’s actual HomePage.tsx. My Projects, Quick Actions, and Recent Deployments are still available through Add Widget, but are no longer shown by default.
  • I’ve also updated the changeset description, which was still referencing the removed patch. Thanks to CodeRabbit for catching that.

I’ve verified everything locally as well: yarn tsc is clean, Prettier is clean, and I tested it live in the browser. Fresh loads show the two-widget default, Restore Defaults matches, Add Widget still lists all five, and the empty-board behavior is confirmed.

The workflow run for the new commit is currently awaiting maintainer approval. When you get a chance, could you please approve it so I can confirm that Build/Lint/Codecov are all green?

Thanks again for the review, and please let me know if anything else needs adjusting.

All cards seem to be wrapped by duplicate titles. Can we fix them ?

RecentlyVisitedHomeWidget, MyProjectsHomeWidget, and
RecentDeploymentsHomeWidget each passed a title to createCardExtension,
but their underlying components (RecentlyVisitedCard, MyProjectsWidget
via SummaryWidgetWrapper, RecentDeploymentsCard) already render their
own title via InfoCard, causing a stacked double-title on each card.
Removed the redundant title from createCardExtension for these three;
QuickActionsSection has no internal title so its title is unchanged.

Fixed, thanks for flagging this! The duplicate titles were caused by RecentlyVisitedCard, MyProjectsWidget, and RecentDeploymentsCard each rendering their own InfoCard title in addition to the title passed to createCardExtension.

I’ve removed the redundant title from createCardExtension for those three. QuickActions doesn’t have this issue since it doesn’t have an internal title. I’ve also verified it in the browser, and each card now displays a single title. The fix has been pushed in the latest commit.
